I’ve written a few apps for the Android market that deal with photography, or at least are related in some way. Check them out. If you have any requests or suggestions, let me know through my contact page.
DSLRNinja Rate My Picture Game (FREE):
This is the FREE Advertisement supported & donation (completely optional) supported version of the DSLRNinja Rate My Picture Game. The “DSLR Ninja” checks out your photographs and gives you helpful information about the properties: Picture format, Exposure, Clipping, Overall Exposure, Rule of 3rds Sharpness, Dynamic Range, Red-Green-Blue exposure with clipping, 4×6 printing size, Compression level, Color and averages, and People (faces). It also rates your photos based on what it considers good from those given properties it checks. It’s a fun and helpful app that is good for novices and skilled photographers alike.
No Nonsense Picture Viewer:
Something to view photos. Something that can load jpeg, png, gif, and bmp of any size (large photos will be dynamically sized to be viewable on the device due to Android memory constraints). Something to see the details of a picture with a simple and easy to use interface that can zoom and move with a single press of the finger. Something that doesn’t use extreme permissions like full Internet access, which frankly isn’t needed for a photo viewer like many so called free and safe apps ask for. This is an image viewer with a goal of being no nonsense and to the point.
Variable Red Screen Light:
A simple yet useful application designed to give you quick access to a variable red light. Red light is better at preserving your night vision, so it is often used in night-time activities like astronomy, astrophotography, and camping. With the variability of the light possible in this application, you can more easily select a light level that fits your task at hand. Your selected light level is saved, so whenever you exit the application you can return knowing how bright your screen will be. The application does not use any special features like Internet access or GPS, so you can be assured in the safety of this application.
DSLR Star Trails Calculator:
(FREE version also available here)
Are you interested in having a helping hand when doing astrophotography with a stationary tripod and DSLR camera? This application can help you calculate estimated maximum exposure times to avoid star trails without the need for a tracking mount. It also has a calculator that you can use for creating star trail photographs by giving you an estimation of how long the trails will be in pixels given inputs about your camera, lens, and exposure time. The three calculators range from a simple two input calculator to one for advanced astrophotography camera users. Also included are some tips and help screens to improve your understanding of the process and to describe each required input for the calculators. This application does not use any advanced features like Internet, so you don’t need to worry about the safety of your personal information. It’s simple, yet does exactly what you need. Here is to amazing astro-photos on a budget!
Image Histogram Generator:
(FREE version also available here)
Are you interested in checking out your jpeg, png, bmp, and gif files to see if they are properly exposed? It’s easy with this image histogram generator. This application loads those formats in any size, large or small, and allows you to see how luminance and color data is distributed throughout the image. I wrote this program so that I could get a nice large detailed tonal histogram of my camera photos as well as images that I downloaded or store on the device. I was even able to display a histogram of an 8MB 100% quality JPEG from my 16MP camera! (with some wait time for processing of course). The application allows you to select an image from the built-in android gallery as well as browse your device with any attached storage like a Micro SD card inserted into your phone or other device. So now you and I can check our work afterward to make sure that the exposure is technically correct as well as check for either red, green, or blue color issues with a nice large full-screen graph of all four. Sometimes only one channel like red can be underexposed or over exposed, causing an issue with the overall photo. I use this program to check for difficult-to-spot issues like that. I’m offering this up on the Android market to help others benefit from my efforts in solving a problem I had.
